Widespread use of advanced mobile devices has led to the emergence of a new class of crowdsourcing called spatial crowdsourcing. Spatial crowdsourcing advances the potential of a crowd to perform tasks related to real-world scenarios involving physical locations, which were not feasible with conventional crowdsourcing methods. The main feature of spatial crowdsourcing is the presence of spatial tasks that require workers to be physically present at a particular location for task fulfillment. Research related to this new paradigm has gained momentum in recent years, necessitating a comprehensive survey to offer a bird’s-eye view of the current state of spatial crowdsourcing literature. In this article, we discuss the spatial crowdsourcing infrastructure and identify the fundamental differences between spatial and conventional crowdsourcing. Furthermore, we provide a comprehensive view of the existing literature by introducing a taxonomy, elucidate the issues/challenges faced by different components of spatial crowdsourcing, and suggest potential research directions for the future.

空间众包调查

先进移动设备的广泛使用导致了一种称为空间众包的新型众包的出现。空间众包提高了人群执行与涉及物理位置的现实世界场景相关的任务的潜力，这在传统的众包方法中是不可行的。空间众包的主要特征是空间任务的存在，需要工人实际出现在特定位置以完成任务。近年来，与这种新范式相关的研究势头强劲，需要进行全面调查，以鸟瞰空间众包文献的现状。在本文中，我们讨论了空间众包基础设施，并确定了空间众包与传统众包之间的根本区别。
